Hi all,
here in germany it is hard due security reasons to get our stuff into the halls.
Especially Batteryboxes with a 9V batterys will be not let in.
So I wonder if there is a chance to supply (in this case church audio CA11/14) these microphones via a powerbank.
I tried to solder an usb cable to 9vbatterieclipcable, but got distortion sounds. Did not work out
Any ideas?
